A NSON JOHN LINDSAY,

QF TQRONTO, CANADA POWER-TRANSMISSION M HANS.

To all whom, it may concern:

Be it known that I, Axsox JOHN Lmosu, of the city of Toronto, in the oounty of York and Province of Ontario, Canada, have invented certain new and useful Improvements in Powt'r-Trnnsmlsslon Means; and i harsh (lIPltUL that the following is a full, clear, and exact description of the some. I

This invention relates to a power-tronsmission moans in which the (lead polio is mounted beside the live pulley upon the hneshaft and osilionml t'o revolve with the live pulley or lin --nhnft by the actuation of the positions the belta lifting means to transfer the holt from the (load polio to the live pulley.

For a lull umlorstnmling of the invention refvrenro is to he llfltl to the following description setting forth one means by which it may he vnrriod into practice and to the ac rompnnving (lrmvings, illustrating tho some, in \\lll('ll Figure l is a perspective view of it portion of the lino-shaft, showing the live and (lend pulleys, the bolt, mul hell-shifting: means, and the operating menus for lit-touting the bolt-shifting moons and Yositioning the (load pulley to I'OVHlVt' with t 10 lino-shalt o2 live pulley. Fig. Z'is n perspective view ofone of the pulleys, showing one of tho rlutch momlwrs, the Clutch member for the utlwr pulley being similar to that. illustrated in this View. Fl 3 is a porn votive View of it part of the belt-shifter, on! Fig. 4 is n nimilo r \'ll of t he come for positioning the (lead pulley on the line-shalt.

llikn figures ofroforenize refer to like parts throughout the spooiliention and drawings The live and dead pul vys l and"), reopen-' tively, tu'o mounted-opal: the lino-shat t 3, or attaehotl to thl-ir zuljiwvnt faces, so that the (lead pulley may rqvolve with the lii'e pulley when the clutch memlmra 4 end 5 are In engagement. Thelive pulley l to mounted to revolve with the iinc'shaft, and the (lead pulley 2 is looselymountml oml longitudinnlly movable on tho line-shaft, so that it will remain stationary, except when the clutch members 4 and 5 are in engagement. To e eet the ion itudinal movement of the dead ulley, the ine-shaft upon the outer y eneirolml by Rule 0 the deitd pulloy is 1001-10 having an arm 7 attached to part 8 to hold the rollnr 6 immovposition, The oolhir 6 has a a collar 6, of the [mining nhlo if: its not Specification of Letters Patent. pollution filed Jamar; 1}, 1995.

cam 9, with which enga es a cam 10 on the hub ll of the o eratingever 12, interposed between the on or 6 and the hub 13 of the dead pulley 2, with both of which it is con-- stantly in contaot. The cams Q and 10 are so formed that when the lever 12 is moved in either direction from the position shown in F'i l of the drawings they will dis lines the hu II from its neutral position um press it in the direction ofthe dead pulley 2 and cause it to move the dead pu-lle toward the live pulley 1, so that the clutc 1 mmnlwrs 1 and 5 will ongnsge and cause the dead and live pulleys to row; ve together until the operating-lever has been returned to its neut "ii in) sitlon, when the dead ulley will lllwl'll to the position from which 1t has been tlisphueti.

Attached to the framing 8 is u guide-arm 14, arranged, roforahly, p'amllol with the line-shaft 3 anti slightly above the lac-it as it passes over the upper portion of the mlleys l and 2, and longitudinally movable through the hide-arm 14 is the shifting-bar 15, hoving t e usual belt-enga 'ng fork 1G omhraoing the bolt 17 to trans or it from um policy to the other. Attached to one arm I!) of the operating-lever is one end of a. shill lug-(0rd 20, which passos around two idlers '31 and 22, suspended, respectively, from the framing 8 am uide-arm 14, t e opposite vnd oi the cord Being attached tonne 0nd of t lltSllll illlg' hot 15. v

Attached to the other end of the shillinghnrl is one end of a second shifting -onl 23, whirl: PHSSQS around two idlers 3t and 25, suspended, respectively, from the guide-o1 In it; and framing 8, the opposite oml of the eord being attached to the other arm 36 of the o whiting-lover. By moving the open gtgii'ag-levor in the direction iridiatmt by urgm marked a the tension on the shilling cont 23 is relieved and the shifting (uni 2U is caused to draw thesii'ifting-bur in the diroe-' arrows markod I: to move the belt from t to (lead pulley 2 toward the live pulley I. As it is an impossibility from a prnetieal mechanical standpoint to shift the belt from the lead pulley to the live pulley-while the former is stationary, it. is necessary to'start the revolution of the loaul pulley so that its'motion may be imported to the belt to enable'tlm shiftin bruto suruvxsfully perform the function of hifting the belt from the dead to the live pulley, and this in attained by utilizin the operating-lover to actuate the halt-sh: ting means and alumi- I no taneously move the dead pulley toward the live pulley, so as to cause the enga cment of the clutch members of the two pu cys. As an interval of time must elapse between the movement of the belt-shifting means and the commencement of the revolution of the dead )ulley, it is advisable in order to compensate iorthis difference in time to make the fin er 1c of the belt-engaging fork longitudina ly movable on the shiftil'ig-bar 15, so that as the shifting-bar moves in the direction of the arrow marked 1) the finger 1.6 will remain stationary a ainst the adjacent edgeof the belt and a] ow the shifting bar to pass through the fin erdiub i6 and complete its movement in that direction without being retarded by the inactivity of the belt, and to employ a pressure-spring to engage the finger 16" and a corresponding retainer l6 on the shiftin -bar 15 to ress the finger toward its neutra position, t 10 spring having sufficient strength to counteract th.) resistance of the belt and enable the finger to move the belt from the dead to the live )ulley as the dead pulley commences its revolution.

To transfer the belt from ,the live to the dead pulley, the (nerating-lever is moved in the direction of the arrows marked 0, which releases the tension upon the shiftingcord 20 and causes the shifting-cord 23 to draw the ,hifting-bar in the direction of arrows marked d, so that the finger 16" Will engage and shift it from the live pulley l to the dead pulley 2.

Connected to the opcratingdever is a connecting means 27, leading to any part of the premises to facilitate the actuation of the operatin -lever. By mounting the live and dead pu eys upon the linc-shaft and transferring the belt from the live pulley to the dead pulley it is ossible-to render the belt inactive except w en revolvin with the live pulley, such inactivity of the elt naturally reducing the wear and correspondingl increasing the length of its life and the life of the driven parts, as the belt when olrthe dead ulley is unable to transmit motion to the ot 1er ulley or pulleys around which it is revolubl Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is
